A photography lens may have some shortcomings if used for video.
One aspect is focus. For photography you set the focus once and then shoot. For video that may be different. You could change the focus while shooting. So that requires that the focus is not only very smooth but also exact and linear. The same goes for with zoom, how smooth and linear is the zoom.
Additionally many photography zoom lenses have a minimum aperture depending on the zoom level, obviously that is a problem for video, you cannot afford to have the exposure change while zooming. Also focus may not be stable while zooming.
I would suggest a lens that has a smooth manual focus and has a constant aperture while zooming. Also test if the zooming feels natural.
Looks like a very practical camera.
However UHD@50/60p using 150Mbs is rather low.
